Title: Process for the conversion of mineral oils and the like, of high boiling point into aliphatic hydrocarbons of low boiling point
IPC: C10G9/34
Filed: 1926-06-02
Abstract: 267,364. Todt, F. W., and Sumpf, P. June 2, 1926. Cracking oils.-Saturated aliphatic oils of low boiling point suitable as motor fuels are obtained by cracking mineral oils in successive stages in retorts containng absorptive bodies e.g. pumice stone, coke &c. under conditions of time and temperature suitable to each stage. The raw materials are vaporized outside the retort and admitted thereto in fractions of equal boiling point which are then heated to the temperature and for the time suitable to the particular fraction. The retort comprises a chamotte lined iron tube 3 packed with absorptive material and enclosed in a fireproof cover 4 heated in a furnace 1. Oil is supplied from a pipe 8 to a tube 6 terminating in a nozzle 7. The cracked products pass through a pipe 9 to a dephlegmator 10. the heavier contents being separated out and collected in a reservoir 12. The lighter gases are liquefied in a cooler 14, 15 and stored in a tank 16, the non-liquefied portion passing to a gasometer 18 to be liquefied by compression. The contents of the reservoir 12 are returned to the retort and the process repeated.

Title: Improvements in or relating to casting machine and continuous casting process
IPC: B22D11/06
Filed: 1956-05-08
Abstract: 806,576. Continuous-casting; rolling. HUNTER ENGINEERING CO. May 8, 1956 [June 20, 1955], No. 14238/56. Classes 83 (1) and 83 (4). In a method of continuous - casting, molten - metal is maintained in the bight between confronting, upwardly-moving, converging portions of roller-surfaces, the space for contact of the molten metal with said surfaces being restricted to between 5 and 15 degrees of the circumference of the rollers extending downwardly from the point of minimum-spacing of said surfaces, and cooling said surfaces to cause solidification of molten metal in contact therewith. Rolls 10 are supported in bearing-blocks 4, mounted in frames 1 and adjustably positioned therein by screws 7 and springs 9a. The rolls comprise shells 13, of, e.g., Cu, A1 and their alloys, steel, Fe, graphite, on cores 14, grooved for the passage of coolant, and are driven from a shaft through gearing 28. Alternatively, if it is desired to adjust the rolls for a range of cast-products of different thicknesses, a pair of drive-shafts may be connected to the roll-shafts through universal couplings. Extending upwardly into the converging space between the rolls is a series of ceramic nozzle-blocks defining a horizontal passage-way 37 and a narrow slit 38, or adjustably-positioned by jacks 31. A molten-metal supply-box 50 communicates with the passageway 37 through a conduit 48 and a port in one end-block 42, and has an overflow-spout 52, the height of which may be adjusted to facilitate the maintenance of the metal level in the roll-pass, preferably between the nozzle-tap and the plane passing through the axes of the rolls, for non-turbulent flow. The rolls may be coated when starting with a mould-release silicone. Conditions and results obtained when casting aluminium are set forth. The arrangement may be such that the rolls work the metal as it solidifies.

Title: Improvements in or relating to Telegraph or like Signalling Systems.
Inventor: DIXON THOMAS BULLITT
IPC: H04L25/06
Filed: 1917-10-02
Abstract: 119,524. Dixon, T. B. Oct. 2, 1917. Selenium-cell and like optically-sensitive relays -A telegraphic receiving arrangement for eliminating the effects of low-frequency disturbing currents comprises a signal-receiving coil adapted to respond to signal currents and disturbing currents, a correction coil adapted to respond only to disturbing currents, and optical means controlled by the receiving coil and the correction coil. The optical means control the amount of light falling on a Wheatstone bridge selenium-cell device. In the arrangement shown in Fig. 1, thesignalling coil 2 is connected in series with the correction coil 5, and is harnessed to a mirror 3. The correction coil 5 is wound on a metal bobbin to increase the damping effect, and is shunted by a resistance 7 and carries a mirror 6. A beam of light from a source 8 is caused to fall on the mirror 3, and after reflection falls on the mirror 6 from which it is reflected to an element 11 which may be a selenium cell device. When signalling currents pass through the coils 2 and 5, the former only is operated to vary the position of the reflected beam 10<11> on the element 11; but upon the passage of low period earth currents through the coils 2 and 5, both coils are operated in such a manner that the position of the beam 10" is unaffected. In the modification shown in Fig. 2, the correction coil 5 is placed in the bridge 20 of a selenium-cell Wheatstone-bridge arrangement, the operating-beam 25 of which is obtained from a source 13 after reflection from a fixed mirror 26 and the mirror 3 of the signalling coil 2. The signalling beam 15 is obtained from the source 13 in the manner described in Specification 100,940, and finally falls on a selenium-cell device 18. The sharp movements of the correction beam 25 due to signalling currents do not affect the current in the bridge 20, but the slow earth currents passing through the coil 2 upset'the balance of the bridge, and the correction coil 5 operates its mirror 6. In the modification shown in Fig. 4, the main coil 2 is provided with an auxiliary winding 5<a> placed in the bridge of a selenium-cell Wheatstone-bridge arrangement controlled by the correction coil 5 in the circuit of which is a damping inductance 33.

Patent GB-843243-A (GB)
Title: A method for the manufacture of spun dyed threads and staple fibres from cellulose solutions
IPC: D01F2/04
Filed: 1958-05-06
Abstract: Lustrous spun-dyed threads of regenerated cellulose are made by spinning viscose or a cuprammonium solution of cellulose containing one or more coloured organic pigments and one or more white inorganic pigments (all of which are insoluble in the cellulose solution), the proportion of the white inorganic pigment or pigments being sufficiently high to cause the threads spun from the solution to show only one colour when viewed from different angles, but not so high as to prevent the threads from having a lustrous appearance.  The spinning solution may contain up to 0.1% by weight of the white inorganic pigment or pigments with respect to the cellulose in the solution.  Specified white pigments are titanium dioxide, stannic oxide, barium sulphate and lead sulphate.  When the pigments are added to viscose it is preferred first to disperse them in a liquid, e.g. water, to which a dispersing agent, such as bentonite, may be added.  In an example, an aqueous dispersion containing 5% of titanium dioxide and 2% of bentonite is mixed with a suspension of Monastral Green and Monastral Blue and the mixture is added to a viscose which is spun into a conventional acid coagulating bath.
Patent GB-1102118-A (GB)
Title: Collagen sponges
IPC: A61F13/20
Filed: 1966-04-01
Abstract: In the manufacture of a collagen sponge for use in surgical procedures, untanned reconstituted collagen tape prepared as described in Specification 1,019,711 is washed successively with a solution containing 0.1% by weight sodium chloride and with water. According to Example 1, the washed and wet tape is added to water containing a minor proportion of acetic acid and is allowed to swell. After agitation and addition of further water to give a mixture containing 0.5% by weight collagen, the mixture is homogenized by pumping.  After placing in a stainless steel tray, the resulting collagen dispersion is frozen and lyophilized to produce a sponge which then is subjected to a heat fixation process to increase tensile strength and to prevent excessive reswelling when placed in water.  According to Example 2, an aqueous saturated solution of carbonic acid is added to the washed and drained tape which then is dispersed by stirring and allowed to swell.  After stirring, the mixture is homogenized.  After placing on a stainless steel form, the collagen dispersion is frozen and lyophilized to produce a sponge which is dried at elevated temperature. The sponge, which is in the form of a sheet having a network of interconnected channels extending therethrough, thereafter is perforated with holes to permit increased flow of liquid into and through the sponge; the sponge may be perforated in die punch apparatus as used for sheet metal perforation.  In order to improve liquid resistance and handling properties the sponge may be tanned, for example prior to perforation, with formaldehyde, chrome alum, tannic acid or phosphoric acid.ALSO:In addition to the network of interconnected channels extending therethrough, a collagen sponge is perforated with holes.  The sponge is in the form of a sheet having two principal surfaces, the holes being normal to, and extendthrough, both these surfaces.  The holes permit increased flow of liquid into and through the sponge and reduce the tendency of the sponge to float away from a wound to which it is applied.  The holes preferably are between 0.1 mm. and 3.0 mm. in diameter and may be spaced 2 mm. apart.  In order to improve liquid resistance and handling properties, the sponge may be tanned, for example prior to perforation, with formaldehyde, chrome alum, tannic acid or phosphoric acid, thereby to provide a water-insoluble tanned sponge body.  Examples decribe in detail the preparation of tanned and untanned sponges from untanned reconstituted collagen tape prepared as described in Specification 1,019,711, the sheet of sponge being perforated in die punch apparatus as used for sheet metal perforation.

Abstract: 579,825. Linear-dimension gauges; indicating - apparatus. HORSTMANN, S. A., and HORSTMANN, Ltd. Sept. 27, 1944, No. 14537/43. [Classes 106 (ii) and 106 (iv)] The invention relates to linear-dimension gauges or other indicating instruments of the kind in which the pointer spindle is' caused to rotate by rolling it over a flat surface and consists in forming co-operating grooves in the spindle 14, Fig. 9, and the surface. The spindle may roll between two relativelymovable surfaces, either one or both of which may be grooved. In the form shown in Fig. 2 applied to a linear-dimension gauge, the spindle 14 of the pointer 15 is situated between a fixed surface 12 and a flat 11 on the workcontacting plunger 10. The grooves on the spindle and the surface are not shown in this Figure. The plunger is guided by two pairs of balls 21 arranged in the angles of an inverted channel member 20 held in position on the base 13 by an adjustable blade spring 22. The movement of the plunger is limited by a stop 24 and that of the balls by stop pins 23. In a modification, Fig. 3 (which does not show the grooves), the pointer spindle 14 is arranged between a flat 11 on the plunger 10 and a plug 30, the plunger being guided by two. pairs of balls 34 in the angles of a channel 35. The plunger is returned to its normal outer position by a spring 38 secured to a plug 39. The latter can be rotated through 180 degrees to cause the plunger to be biassed inwardly to measure the extent to which the plunger is pulled out , of the casing. The plugs 30, 39 are kept in position by a plate 42. In another form, Fig. 5, which does not show the grooves, the work-contacting plunger 57 operates a lever 55 to which are secured threads 53 passing round the pointer spindle 50 and kept taut by a spring 56, movement of the threads causing the pointer spindle to roll against a fixed surface 52. The spindle may carry a pointer instead of a mirror.
